16. Upcoming Activity Rulemaking for Approved Training (121 and 135 for start) Multi-disciplinary approach to maintenance fatigue Audit of normal operations Impact of new technologies on maintenance training

17. Overview • AVS Chief Scientist Program • Maintenance HF Sample Activities • Upcoming Activities • Challenges/Myths

18. Challenges/Myths (1 of 2) • Employee training/certification • Ab initio • Continuation • Is today’s workforce ready? • Is our aviation maintenance workforce the world’s best • Selection process for maintenance personnel • Maintainability of new technologies? • Design of technical documentation “systems”

19. Challenges/Myths (2 of 2) • Repeated studies show: • Installation errors • Failure to documentation • Should smart A/C require less skilled maintenance personnel? • Compare to automotive industry • Small GA shops don’t need SMS, error reporting, etc.
